Abstract: An apparatus, system and method for natural refrigeration comprising a naturally refrigerated cooler and ice bin containing an ice bin with a refrigerator compartment suspended within it. The ice bin and cooler compartment are configured such that when ice cubes and the resulting cold water are loaded into the ice bin, the ice cubes and resulting cold water surround the refrigerator compartment and act to remove heat from inside the refrigerator compartment.

Abstract: A heat exchanger is provided for warming fuel prior to introduction of the fuel to an engine, the heat exchanger including: a fuel inlet and a fuel outlet; a heat exchange matrix having heat transfer components past which the fuel flows between said inlet and said outlet and which are arranged to be heated; and swirl inducing means arranged between said inlet and said matrix arranged to cause fuel from said inlet to swirl prior to entering said matrix. By causing the fuel to swirl prior to entering the heat exchange matrix, entrained ice in the fuel can be caused to concentrate at an outer region of the heat exchanger thereby allowing fuel to continue to flow through the heat exchanger to the engine even when ice is present in the fuel.

Abstract: An adaptor enables a convective treatment system to be modified for cooling by providing a bath of pressurized, cooled air intended to lower the body core temperature of a person. The adaptor may be constructed for being coupled between a blower assembly that provides a stream of pressurized air and a convective treatment device that receives the stream of pressurized air, distributes it, and provides it for bathing the body of a person in a general bath of cooled air in order to produce a desired clinical effect such as prevention or alleviation of hyperthermia or for thermal comfort. Such an adaptor may be embodied as an enclosure having a shaped internal cavity. The shape is useful for effectively and efficiently distributing a flow of pressurized over, around and through a bed of ice disposed in the cavity. Ports are provided in the enclosure for introducing a flow of pressurized air into, and receiving a flow of pressurized air from, the cavity.

Abstract: A drinking vessel includes an interior portion that holds pellets or chips of dry ice that cool a beverage in the glass while the beverage is being consumed. The interior portion can be a part of the glass or it can be a detached piece usable in different vessels. Either way the interior portion includes holes that allow the beverage to freely flow around the dry ice while the holes are small enough to prevent the dry ice from entering the portion of the vessel where it could be accidentally consumed.

Abstract: A portable housing holds a quantity of ice and the melt water from the ice or cooled water or cooled liquid is circulated through a heat exchanger. A blower circulates air from the room through the heat exchanger and back into the room for cooling the room. The housing includes a relatively large chamber for holding the ice and a relatively smaller chamber in which the blower is disposed. Melt water from the ice, or cooled water or cooled liquid, is pumped through the heat exchanger and from the heat exchanger the liquid flows by gravity back to the ice and water chamber.

Abstract: An apparatus for cooling at least one fluid includes at least one fluid system comprising at least one fluid line, and a metallic unit. The fluid system is arranged in the shape of a concavely depressed coil with a top and a bottom. At the bottom of the coil an opening is defined. The metallic unit incorporates the at least one fluid system. The metallic unit has an upper surface in which is defined a concave depression, and the concave depression has defined therein a drain which extends through the metallic unit. The concave depression of the metallic unit is aligned with the concavely depressed coil, and the drain defined in the metallic unit passes through the opening at the bottom of the at least one fluid system.

Abstract: A thermoregulating container provides for the heating and cooling of food and drink. The container is insulated and includes a heat exchanger system that can maintain the temperature of the contents of the container. The device may include modular elements that can detachably attach to one or many containers to selectively heat or cool the contents of the container(s). A first embodiment container includes at least one passage through the walls thereof, for conducting a heat exchanging fluid (water, refrigerant liquid, etc.) therethrough. The container passage(s) communicate with an attached reservoir module when such a module is attached to the container. When the module is attached, a heat exchanging fluid is circulated through the passage(s) in the container walls to heat or cool the substance therein accordingly.

A pump continuously circulates the liquid in the closed loop, with the heat exchanger through which air is blown is part of the closed loop system. The apparatus may also be used as a portable heater by using hot water instead of cold water in the heat exchanger.

Abstract: A beverage cooling system has an ice storage bin having a mechanical agitator disposed therein. The ice storage bin includes an opening at a bottom portion thereof, and the mechanical agitator is actuable to mechanically agitate ice in the ice bin and mechanically force ice through the opening. An ice guide is disposed adjacent the opening in the ice storage bin. A cold plate is disposed adjacent the ice guide. The cold plate has an inclined upper surface thereof and includes at least one beverage line disposed underneath the upper surface. The ice guide is positioned to deflect and guide ice onto the inclined upper :surface of the cold plate, wherein the ice is moved along the upper surface by mechanical force provided by an actuation of the agitator.

Abstract: A cold plate for cooling different beverages drawn from supply cylinders, the cold plate being formed by a rectangular base over which is a run-off roof defined by sloping end and side sections. Embedded in the cold plate are cooling coils terminating in input and output terminals that project from the underside of the base, the coil inputs being coupled by upstream lines to respective supply cylinders, the coil outputs being coupled by downstream lines to a soda gun to selectively dispense the beverages. The cold plate is received in the well of a thermally-insulated sink having an open bottom bordered by a rectangular ledge. The base of the cold plate is seated on the ledge in spaced relation to the sides of the well to define a gutter in which there is a water drain. The sink is filled with ice cubes that cover the exposed surfaces of the cold plate and are in heat-exchange relationship with the cooling coils to cool the beverages flowing therethrough.
